Lab 7: ERRO 041 [allarewelcome] Got error &{FORBIDDEN}

(my encounter and escape from ERRO 041

when I try to get config (genesis block) for peer0.org2 I have above error, on second use, first time it works without error

# fetch genesis block
$ peer channel fetch 0 Org2AddedConfig.block -c allarewelcome -o orderer.example.com:7050
2019-11-09 18:31:20.732 UTC [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
2019-11-09 18:31:20.735 UTC [cli.common] readBlock -> INFO 002 Got status: &{FORBIDDEN}
Error: can\'t read the block: &{FORBIDDEN}

first time I send update to the network for approval with

$ peer channel update -f org2SubmitReady.pb -c allarewelcome -o orderer.example.com:7050

it works, if I try to do the same, always have above error

$ peer channel update -f org2SubmitReady.pb -c allarewelcome -o orderer.example.com:7050

Error: got unexpected status: BAD_REQUEST -- error authorizing update: error validating ReadSet: readset expected key [Group]  /Channel/Application/Org1MSP at version 1, but got version 0

the problem is when I try to join org2 to channel and always have above errors

seems related with Principal deserialization failure (MSP Org2MSP is unknown) for identity 0

FINAL FIX: after some debug, I re-start generate ALL files to add org2 to network, start in section Adding a New Organization to Our Channel

# inside cli container, grab latest configuration definition from the network
$ peer channel fetch config blockFetchedConfig.pb -o orderer.example.com:7050 -c allarewelcome
.....follow docs, creating files until we have reach line
# send update to the network for approval
$ peer channel update -f org2SubmitReady.pb -c allarewelcome -o orderer.example.com:7050

now after re-send the send update to the network for approval, with

$ peer channel update -f org2SubmitReady.pb -c allarewelcome -o orderer.example.com:7050

the running peer0.org2.example.com container crash, and stop, I delete it, and re-start it, and it start to work

I don't know if the solution is deleting the container or re-create the files and send the network update to approval?
maybe some expert can clarify me.....or next time I try first drop container, but I don't want to drop containers, in this case I dont any choice it crash

# start and check it all works well
$ docker-compose up -d peer0.org2.example.com 
$ docker-compose logs -f peer0.org2.example.com

now I can get config/genesis block again and join channel with peer0.org2

# fetch genesis block
$ peer channel fetch 0 Org2AddedConfig.block -c allarewelcome -o orderer.example.com:7050
2019-11-09 19:29:56.112 UTC [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized

# join channel
$ peer channel join -b Org2AddedConfig.block
# list channel
$ peer channel list
Channels peers has joined: 
allarewelcome
# do the same for peer1.org2
$ PEER=peer0
$ export CORE_PEER_ADDRESS=$PEER.org2.example.com:7051
$ peer channel join -b Org2AddedConfig.block
Channels peers has joined: 
allarewelcome
# list channel
$ peer channel list

done problem solved, I can continue my HL adventure
